Have you ever tried to manage a Python project and ended up in dependency hell, only to realize that it was actually the newest version of pipenv that was broken, or a package that was missing from Anaconda, or poetry was using the wrong version of Python?
If you have ever had to distribute or deploy a Python project, or replicate the dependencies of said project on a different machine, you have probably found yourself frustratingly debugging your deployment, trying to figure out why it works on your machine and not on your colleagues, or spent hours trying to find out how to activate a conda environment inside a Docker container.
If you have, then venv-cli might be for you.

Building software is not always easy. There are challenges like making sure the different parts of the software can talk to each other, ensuring data is accurate across the system, and dealing with tasks that are spread across different parts of the software. To deal with these challenges, it’s important to use good methods for developing software. Three such methods are Behavior Driven Development (BDD), Acceptance Test-Driven Development (ATDD), and Domain-Driven Design (DDD). These methods are helpful on their own, but when used together, they can really improve how we build software using the microservices architecture.

Monday the 24th of October seemed a day just like any other. I stepped into a modern-looking building in the wonderful city of Warsaw and didn’t know this might change my life forever! :o Well, not really about the forever part, but it was a step outside my regular day-to-day development work.
This year Angular turns 6, and it has not been standing still! I’ll try to put in a few lines about what I feel could improve our daily project experience.

A fishtank serves as a perfect analogy for a monolith frontend application. Your boss (product owner) wants new fish (features) to impress the visitors (end-users), and probably expect you to just make it work. The visitors expect to see happy and healthy fish (expect the features to work). As a caretaker (developer), your task is to keep both your boss and the visitors happy whilst taking care of the technicalities that keep the fish healthy, but you know that placing some fish together is risky (might cause bugs or errors). You’ll also need to install specific water plants (dependencies) for some fish to thrive, but they’ll have a negative impact on some of the other fish.

When we talk about connectivity, regardless of whether it is for our handheld devices or IoT devices, there are a plethora of technologies and network operators, where you are easily convinced that it is just a matter of subscribing. Then you are connected and can exchange data. They have you covered, so to speak. But if that was the case, how could I have the experience I did?

This blogpost covers the following areas:
· Angular and OWASP Top 10
· A dive into three important and fundamental security concepts
OWASP stands for Open Web Application Security Project. The OWASP Top 10 is a list you need to know, as it is a list of web security risks from the OWASP foundation. It tells you where to focus your security effort, as it represents the most critical risks.

The goal of this how-to is to get you ready to develop a Dynamics 365 Sales application your customers can use right away!
If you haven’t worked with Dynamics 365 before it can be pretty difficult to find the right documentation for the right business application and get started developing. If you want to get started with a Dynamics 365 application other than sales, please look at the Dynamics 365 documentation: https://docs.microsoft.com/en-us/dynamics365/. But if you are new to Dynamics 365 you will still get something out of this read.

In my last blog post about Spring JPA, I went through a very simple example to demonstrate what Spring JPA is and how to use it. I want to elaborate on this very simple example and show what to do in JPA if you want to create a query where you join tables, which is something you have to do a lot when fetching data from a relational database.

I wasn’t sure how to start and how JPA worked. I managed to set it up but I needed a very simple example to implement and use it. So, I am writing this guide for anyone with that exact issue. You get the beginner’s steps from annotations to repository and query methods in this quick guide. I hope you find it useful.

A frequent question to my last blog is whether the industry can adopt the best practices developed at CERN. I will try and answer this question. More specifically I will zoom in on problems in IoT streaming data:” Can the experiences from CERN be used to create a data foundation for IoT streaming data in the industry?”

At BESTSELLER we run multiple Kubernetes clusters in multiple clouds, which gives us some assurance that even if one provider or one region is degraded we are still able to serve our customers. But multiple clusters, multiple clouds and multiple teams can be a bit difficult to grasp as an engineer.

A non-intrusive library is for everyone who wants to implement any kind of integration the easy way. When using Camel “integration”, it covers connecting (almost) any kind of source with (almost) any kind of sink - with the opportunity to perform custom processing and transformation of data in between.

We have all heard it, and the UN Sustainable Development Goal No. 6 highlights it — clean (drinking) water is a scarce source that we need to protect. But how are leaks in pipe networks actually discovered if the leak does not manifest itself as a new water fountain in Mrs Smith’s backyard?

When running a lot of microservices, a lot of things happen! You need observability to know what’s happening, the duration of it, and how often. In Danske Bank, we’re running a mobile bank across 5+ markets with more than a million users. I’ll show you how to instrument your C# code for observability.

I’m not one to tell Turing-award winners like Hoare how to design programming languages, but I will say that I don’t think null is inherently bad. I will discuss why that is, when you should and shouldn’t use null, and how to elegantly handle null-values over in the following two blog posts…
